THE YONGALA'S PROBABLE
TRACK.
DESCRIPTION OF THE COASTLINE.
Captain D. Kerr, master of the Adelaide
Steamship Company's steamer Marloo,
which arrived at Port Adelaide from Western
Australian ports on Wednesday evening,
heard with deep regret the news of
the missing steamer Yongala. Captain
Kerr was for a long time engaged on the
Queensland coast, and when asked for a
description of the track usually taken by
steamers, he said:
"The usual track from Dent Island is
to steer half a mile off the Dent Island
lighthouse. Then to steer a various course
in passing the many islets in a north-west
direction until past Gloucester Head, one
and a quarter miles distant, which is at
the northern entrance to Whitsunday
Passage. From there a direct course is taken
north-west for about 70 miles, which carries
the vessel to about six miles off Cape
Bowling Green Lighthouse. The steamer
then steers northwest for about 28 miles
which would bring her to the Cape
Cleveland lighthouse. Cape Cleveland
forms one of the sides of Cleveland Bay,
in which Townsville is situated. A further run
from the cape of ten miles takes
the vessel into Townsville Harbor.
Captain Kerr called it as it was. No more beating about the bush about the inshore, inside route taken by masters of coastal steamers. This was the very thing the Inquiry wanted to avoid. But not only did Captain Kerr call them out, he provided confirmation with detailed instructions (directions).
It is interesting to note that the Yongala wreck is 11 miles off Cape Bowling Green and the course, as described, was 6 miles off the coast. This suggests that Yongala was 5 miles out of her course, further out to sea.
Following the ordinary fine weather course as
described the vessel would pass Nares'
Rock, five and a half miles to the westward
of that danger. When abreast of
Cape upstart, the inner edge of the Barrier Reef
would be about 13 miles distant,
and the Queensland coastline about 10 miles
distant.
The Barrier Reef is the nearest
submerged danger. It is covered with
boulders, partly dry at half ebb time. At
high water these boulders are completely
covered. There is deep water close to
the reef. From abreast of Cape Upstart,
fairly clear water is met with until in the
vicinity of Cape Bowling Green, off which
three to three and a half miles from the
mainland there are some outlying reefs.
This is interesting. There was an immediate threat off Cape Bowling Green in the form of outlying reefs, 3.5 miles out. Under normal circumstances, masters set a course 6 miles off the coast at this point, allowing a slim margin of 2.5 miles.
When Yongala went down 11 miles off Cape Bowling Green the course might very well have been intentional, giving Captain Knight sea-room to maneouvre and avoid running aground. Deeper water would also have been the choice in severe storm conditions.
But anything beyond this brought the Barrier Reef into sharp focus, another imminent threat.

Nares' Rock is only 26 ft. high, and therefore
is very dangerous. Holbourne Island,
close by, is 360 ft. high. I do not wish to
theorise as to the fate of the Yongala."
Within the reef along the coast there is
generally a calm sea, owing to the reef
acting as a breakwater. The inside route
is one that requires careful navigation,
particularly at night, when the reef cannot
be discerned at a greater distance than
half a mile. In daylight it is said to be visible
at a distance of four miles from the bridge
and seven from the rigging. Sailing vessels
which take the inner passage usually anchor
at night for safety.
Again the point is well made that this was a dangerous route in conditions of poor visibility. But Captain Knight was experienced and able to find the sensible middle course.
Steaming from Mackay to Townsville, a
distance of 208 miles, the coastline is
studded with numbers of small islands,
and in thick weather navigation is extremely
difficult. Shortly after leaving Mackay several
small groups of islands, the largest being the
Blacksmith group, are encountered. These are
not difficult to avoid in clear weather, but if the
atmosphere be at all hazy great care has to
be taken owing to the strong currents.
Dent Island, mentioned in the telegrams,
lies at the southern entrance to Whitsunday
Passage, and is provided with a lighthouse.
It was from this lighthouse (says the Melbourne
"Argus") that the Yongala was last seen. It is a
matter for regret that there is no telegraphic
communication between the lighthouse and
the mainland. Between Dent Island and the
the mainland. Between Dent Island and the
Queensland coast is a small islet called
Pine Island. Whitsunday Passage at this
spot is only two and a half miles wide.
Behind Pine Island is Cod Bay, a sheltered
harbor, often used by ships in bad
weather. The search vessels expected to
find the Yongala in this bay.
Contrary to previous press information, Dent Island did not have direct communication with the mainland which might explain why the warning of a cyclone off Bowen was not relayed to Flat Top AND Dent Island.
If Dent Island had received the warning, this could have been relayed to Yongala via flag signals - daylight (5.00 p.m.) and reasonable visibility at that stage.
It is a further likely reason why the Inquiry insisted that Yongala passed Dent Island at 6.35 p.m. well after dark and because Dent did not have Morse, a warning could not have been issued to the steamer rendering direct communications with the mainland a moot point.
This was clearly a weak link in the culpability of Queensland State. There should have been communications between Dent Island and the mainland and there should have been a Morse lamp.
Perhaps this is why Adelaide, the port of register for Yongala, insisted that the Inquiry be conducted in Brisbane.
Come on Queensland, own up to your share of culpability in this disaster!!
